thanks!

I notice in your signature line that you've got 2 MP60s. I'm building an in-wall 320 gallon tank (6'x3'(34" actually)x30") in a house I'm building right now. Still trying to decide how to power supplemental flow on top of the return pumps given that the tank will be open on both long sides. All of my pumps will need to be on the far sides of the tank, so I was thinking either 4 MP40's or 2-4 MP60's

How do you have your MP60s arranged in your tank? If they're opposite each other, do you find they're powerful enough to not leave big dead spaces in the middle of the tank?
